Airline reviews

The food on this flight was just terrible. I have a wheat allergy so when booking I ask for gluten free options. The food given was inedible. The bread rolls were rock hard. Once board I was given one and the only thing I could do was eat the chicken slice and piece of tomato on it. Also given was 4 small cubes of fruit, 2 watermelon and 2 pineapple and a bottle of water. My husband had a regular meal and found his very average. Then the evening meal was also disappointing! Some dried out fish with spinach and 3 sticks of dry white sweet potato. No sauce …. 😳 again, the same fruit and water. The passengers had to wait a long time for the dinner food to be served. My husband just wanted to eat and go to sleep so he was a bit annoyed about that. We got off the plane and I was feeling quite hangry. Not enough food or a good eating experience. Emirates used to be a flight we looked forward to… now we are considering looking at other companies for the future.

Not that good The crew in the plane were rim professional & almost lost in their work distribution

The crew manager let the staff down by not ensuring special dietary requirements meal were coming in drips . The poor cabin crew did not stop . If organised the cabin could take a short break ..The cabin crew were AWESOME UNLIKE THIER TWO MANAGES!

Overall good but one thing I didn’t understand is why they didn’t allow me to pick my own seat.

Me and 2 other rows were forgotten during food service. We waited over an hour before they finally served our food. Then only had what was left. They did apologize. Also, they locked the bathroom due to turbulence and my 4 year old had to pee himself because they wouldn’t unlock it for him.

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Well emirates since after covid recovery their service became much poorer than before , old planes to some destinations, untrained staff , rude , inflexible, and poor food, this specific flight the plane felt like in the 90s , and staff behavior was rude due to usual incidents in these flights for some destinations, i understand this but they pit everyone at the same basket, a readiness to be rude anytime

Ask for extra blanket if needed. Also middle seating have bad access position to access reading light and vent so only choose those seating if traveling as family or friends, etc.

Premium economy on Emirate A380 is simply the best non-business class product. In fact its probably better than many business class if the seat isnt lying flat. The food and service is close to perfect!

I booked the air tickets through Kayak for traveling to India. I wasn't sure how to tackle the ticket booking process but it was so much easy with the Kayak , Surprisingly I even found the Indian branch of Kayak which I used for the domestic travel. All in all , it's most convenient site to use here as well as abroad. I will definitely use Kayak for my future travels.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

Food could have been better especially the breakfast. Overall it was a good flight

No birding was given for next trip on same carrier, food was very moderate.

A couple of minor delays in boarding but very professional and efficient staff.

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

their gluten free lactose meal is the best, I have never been satisfied with my flight meals. I definitely enjoyed my flight and the chair is very spacious for economy. I'm so glad Delta is my flight way back to NY.

My seat was so uncomfortable, and the headrest was broken. Very very disappointing for the price I paid.

The hard product, food, and service are far superior to their North American counterparts

Cons: "Not to have 2 distressed cats on board meowing non stop for 10 hours."

Movie selection was ok, but could be better. Would like to see greater selection of newer movies.

It was a nightmare. I booked business class ticket from Ediburgh to Beirut via Istanbul to attend a funeral. I had a wonderful experience flying to Istanbul from Edinburgh. Then I could not get a boarding pass issued to Beirut. It seems that although they booked me and I had a reservation number, I had no seat allocated and the flight was full. I was asked to go from one desk to another and made to wait for 2 hours. I missed my flight as I did not have a seat assigned and it was full. The only option was to put me on the next flight, 6 hours later, for a fee of over $400. They said that was the best they can do to 'help me' and to 'take it or leave it'. Well, I was not about to be bullied; I stood my ground. I booked and paid premium for the journey, which was confirmed. The eventually accepted to not charge me extra and i waited a total of over 8 hours in the airport with no compensation. On top of my grief with the risk of missing the funeral service, I had to put up with their indifference and condescending attitude. They spoke about me in Turkish thinking I would not understand (I hold a British passport) in front of me. When they eventually handed my passport and boarding pass back to me, I showed them I was born in Istanbul and that I understood everything and said a condescending 'thank you' back to them in Turkish. You should have seen their faces. I said that consumers have rights and it is a shame that Turkish Airlines does not have good customer service to at least acknowledge and apologize for errors committed by the airline. Blaming the me, the client, for such an error and placing unreasonable ultimatums, rudeness and dismissiveness to be rid of me, particularly when I was vulnerable and visibly grieving was really shocking... The airline taints the city of Istanbul and the people of Türkiye. Such a shame.

There was a Turkish Airlines employee sitting in front of us, we noticed from her conversations we witnessed with the cabin crew and the fact that she boarded business class. She was sat in 16A. Firstly she was talking loudly the majority of the flight with two other men, one of which was leaning over the seat in front of her. This was disturbing as they were talking loudly and we were not able to sleep. The 12 hour long flight turned into a nightmare, even the noise cancellation didn’t work for their chatter. Secondly she requested extra meals from the crew for her male friends. We believe the meals came from business class. They also took their e-cigarettes out and were caught the cabin crew, but no further action was taken. Sitting in economy and seeing this is extremely disheartening. Next time I will book Emirites, I don’t think their staff would be allowed to behave like this.

Okay experience, seats had a very poor legroom and width. Very uncomfortable for long journeys.

The flight was very dirty and the food was very bad

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

I am writing to express my extreme dissatisfaction with the recent flight experience I had with your airline. This has been one of the worst travel experiences I have ever encountered, and I feel compelled to bring it to your attention. Firstly, I missed my flight due to what I perceive to be a lack of clear communication and coordination on the part of your staff. There was no remorse or apology from the airline's representatives, which further exacerbated the situation. As a result of missing my flight, I was subjected to a 24-hour delay at the airport, where I had to spend a significant amount of money to rent a hotel room and cover other incidental expenses. Additionally, since my baggage was already checked in from Tanzania to Turkey, I had to purchase essential items for the 24-hour period. What truly dismayed me, however, was the discourteous and unprofessional attitude of your staff. Their lack of empathy and understanding only added to the stress and inconvenience of the situation. I have been traveling abroad for over 20 years, and I can confidently say that this experience has been the worst I have ever encountered. As a result, I am compelled to reconsider ever using your airline again for future travel. I strongly urge you to address the issues I have raised and take immediate steps to rectify the situation. Additionally, I expect a formal apology and a refund for the expenses I incurred due to the airline's negligence.

Flight canceled and uncanceled. I had already rebooked and so have to pay for both. No one is willing to admit fault

Friendly crew. Computer systems had trouble keeping my Star Alliance status linked to my reservation. Inflight Wi-Fi was slow and expensive. No standard power outlet, but medium-power USB-C port slowly charged my laptop. No option to buy whisky in economy.

I canceled this flight after turkish airlines did not provide any consideration for a death in the family while in Singapore

Online was good boarding also but a child was crying all the way with no intervention from crew member.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

One thing is very important is you people not giving seat arrangement together to couple, senior citizen. You have to take care of senior citizen. Do not look about money. Money is not important everywhere. Make relationship strong is very very important. I like Etiyad air line out of all air line. Food was hot and delicious. Air hostess gave very good service, nice attitude, very good behaviour. I gave 10 out of 10 marks. Thanks Jivraj

1.Aircraft Comfort: The aircraft type was quite small with non-reclining, cramped seats that significantly lacked comfort. 2.In-flight Entertainment: There was no provision of in-flight entertainment screens or Wi-Fi for the majority of the flight. 3.Boarding Process at New Abu Dhabi Airport: Despite the move to a new airport, which promised enhanced experiences, the use of buses instead of jet bridges did not meet expectations, causing inconvenience. 4.Gate Change Communication: A last-minute gate change was poorly communicated, resulting in a long and difficult walk.

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Boarding was quick and efficient. Ground staff were pleasant and courteous. Food was tasty, portions were good for me. Food containers kept slipping on the tray. Tray would look better with an anti-skid tray mat. I had the bulkhead seat which was very uncomfortable for couple of reasons. Aircraft is designed with no throughput to move across aisle to aisle. Passengers kept jumping over my legs to get from one side to the other to use the toilet. Secondly I had a mother and 9 month baby next to me. Mom had to hold baby for 12 hours in her lap as he did not fit into the bassinet. Half the baby was on my lap during the flight. Aircraft temperature was very cold - light attendant said it was the central cooling and nothing could be done about it. Movie selection was very poor old and outdated.

Crew did not cooperate… I just asked water twice for one crew member and she didn’t get anything.. and when I asked other crew member he gave me water and he was not respectful.. I kept Hindu non veg meal chicken .. when I get my turn chicken was not provided and then they gave me veg paneer and green peas curry which I don’t like..

Very very bad service very tight seats never ever flying with Etihad again

Food was not good. Tasted stale and dry. When seats moved to lie flat they were very uncomfortable. No free internet. No live tv. Not flight map. Arrived safely and on time. Boarding easy.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working. - Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

They allowed some guy to move seats after 3hours of him being next to someone very sick, There were several empty seats, but they moved him to mine. I find that incredibly inconsiderate and should not have been done.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Staff were very helpful. The free WiFi for messages was also very useful to keep in touch

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

The crew on board were all very pleasant and happy to help. The flight had the old business class seats. The departure board in the business lounge did not update and kept on saying ' gate open' but never said boarding. When I got nervous about the departure time and walked to the gate I was told off rudely for being late.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Crew and boarding fine. Flight delayed, then delayed again after boarding.
